Singer and four-time Grammy victor Michael Bublé is officially retiring from music following his son's battle with cancer.

News about Bublé's son Noah's cancer battle broke two years ago when the singer suddenly pulled out as the host of the 2017 BRIT Awards.

And speaking about the 2016 diagnosis on the Today Show, the singer said the support of fans and well-wishers had helped his family in what was "the worst possible thing that you could hear as a parent and maybe as a human being".

"My wife was the same and even though I was the stronger of the two of us, I wasn't strong. I'm sorry, I can't make it to the end of that sentence".

The crooner admitted he no longer "has the stomach" for fame and has "changed his perception on life" following his son's cancer diagnosis aged 3.

It seems he has also been on a life-changing personal journey which forced him to recognise he had been unhappy with his life and career even before Noah's diagnosis.

Thankfully, Noah is now in remission.

Michael and Luisana have two other children - 11-week-old Vida and Elias, two.

Both of them put their careers on hold to deal with their son's medical crisis. "I'm retiring from the business", he starts, adding: "I've made the flawless record and now I can leave at the very top". "I was embarrassed by my ego, that it had allowed this insecurity", he told the Daily Mail.

He said: 'I decided I'll never read my name again in print, never read a review, and I never have.

"I truly thought I'd never come back to music", he said in July. Although Noah'shealth has since improved, as we've told you in 2017, the battle changed his father forever. Is this all there is? My perception of life. There was never a choice [when Noah was ill]'.

Buble and actress/model Lopilato got married in 2011 in Buenos Aires. So once when Luisana had to go back to Argentina I said to them, 'Come over to the house, let's drink, order pizza, play video games and jam'.
